There is a uniform electric field for regions near the surface of the earth equal to -150 N/C K. (It is directed toward the centerof the earth or simply downward). Determine the electric flux for each of the following.
a) the floor of the room, dimensions=9m*14m
b) a wall of the room, dimension=14m*3m
c) a book cover of a dimension = 9cm*14cm that is tilted openat a 45 degree as the book rests on the table.
d) a sheet stretched tight with each corner attached to one ofthe four corners of the room(at any height) such that the edges ofthe sheet abut the walls of the room.
